Conclusion: A standardized nursing-terminology-based electronic nursing record system allowed us to monitor the variations in nursing practice with regard to preventive pressure-ulcer care in intensive-care patients with and at risk of pressure ulcers. We found that pressure-ulcer prevention care was provided at frequencies much lower than the recommended guidelines. Further studies on identifying the factors affecting pressure-ulcer prevention care and ways to improve the quality of that care are needed. (Source: International Journal of Medical Informatics).
